State regulators conditionally approve first Clean Energy Implementation Plan for state’s largest utility

Puget Sound Energy aims to serve more than half its customers with clean energy by 2025


LACEY, Wash. - Today, the Washington Utilities and Transportation Commission approved Puget Sound Energy’s first Clean Energy Implementation Plan (CEIP) required under the Clean Energy Transformation Act, with conditions to address certain shortcomings in the plan.

The approved plan proposes that PSE will serve 63% of its sales of electricity with clean energy by 2025. In its order, the commission emphasized the company needs to consider potential cost-savings provided by recent federal legislation and the company needs to comply with clean energy transformation standards at the lowest reasonable cost.

The commission also approved other specific targets proposed in the CEIP, including a voluntary target for distributed energy resources.

In its decision, the commission ordered PSE to update its specific target for demand response technology, increase its support for community solar instead of leasing solar resources to customers, and update its evaluation of utility-scale batteries as a resource to meet demand.

The commission found that PSE’s plan failed to describe the specific actions it will take over the next four years, and it was not sufficient for PSE to state that it was waiting for bids in response to its request for proposals. The commission declined to reject the plan, noting that the CEIP was the company’s initial plan under CETA and that the company could address the plan’s shortcomings in future filings.

In its order, the commission made clear that the failure of any investor-owned utility to describe its specific actions could result in the commission rejecting the CEIP or assessing penalties, “Specific actions are so critical to the CEIP that any future CEIP that fails to provide specific actions will likely be rejected and/or subject to penalties.”

PSE is required to file an update to its CEIP with the commission by Nov. 1, and its next CEIP is due in 2025.


In December 2021, PSE filed its final CEIP in Docket UE-210795 with the commission.

The Clean Energy Transformation Act (CETA) requires regulated utilities to submit Clean Energy Implementation Plans to the commission every four years for approval. The CEIP must demonstrate the utility’s progress toward achieving CETA standards. The plan must propose targets and identify specific actions to pursue cost-effectiveness, safe and reliable systems, customer equity, and burden reduction for vulnerable populations and highly impacted communities. The commission must approve, approve with conditions, or reject each investor-owned utility’s plan.

Bellevue-based PSE provides energy service to more than 1.2 million electric customers and 860,000 natural gas customers in eight Washington counties: Island, King, Kitsap, Kittitas, Pierce, Skagit, Thurston, and Whatcom. PSE also provides natural gas service to more than 800,000 customers in six Washington counties: King, Kittitas, Lewis, Pierce, Snohomish, and Thurston.

The UTC is the state agency that regulates private, investor-owned electric and natural gas utilities in Washington. It is the commission’s responsibility to ensure regulated companies provide safe and reliable service to customers at reasonable rates while allowing them the opportunity to earn a fair profit.
